越來越java.io.FileNotFoundException爲HttpURLConnection的

Question

我想實現簡單的登錄窗口，但它給文件未發現異常.... 找遍了很多關於這個，但它沒有運行...

保護字符串doInBackground（字符串...空隙）{

try { 
     Thread.sleep(4000); 
    } catch (InterruptedException e) { 
     e.printStackTrace(); 
    } 
    String type=voids[0]; 

    String url="http://192.168.0.105/rootlogin.php"; 
    if(type.equals("initlogin")){ 
     try { 
      String un=voids[1]; 
      String up=voids[2]; 
      URL u=new URL(url); 
      HttpURLConnection huc= (HttpURLConnection) u.openConnection(); 
      huc.setRequestMethod("POST"); 
      huc.setDoOutput(true); 

      huc.setDoInput(true); 
      OutputStream os=huc.getOutputStream(); 
      BufferedWriter bw=new BufferedWriter(new OutputStreamWriter(os,"UTF-8")); 
      String post_data= URLEncoder.encode("un","UTF-8")+"="+URLEncoder.encode(un,"UTF-8")+"&"+ 
        URLEncoder.encode("up","UTF-8")+"="+URLEncoder.encode(up,"UTF-8"); 
      bw.write(post_data); 
      bw.flush(); 
      bw.close(); 
      os.close(); 

      InputStream is=huc.getInputStream(); 
      //InputStream error = huc.getErrorStream(); 
      BufferedReader br=new BufferedReader(new InputStreamReader(is,"ISO-8859-1")); 
      String result=""; 
      String line=""; 
      while ((line=br.readLine())!=null){ 
       result +=line; 
      } 

      br.close(); 
      is.close(); 
      huc.disconnect(); 
      return result; 
     } catch (MalformedURLException e) { 
      e.printStackTrace(); 
     } catch (IOException e) { 
      e.printStackTrace(); 
     } 
    } 
    return null; 
} 

Answer 1

賠率是你的PHP文件不位於您的服務器的根目錄下。檢查文件路徑並更正URL。

Answer 2

bw.close(); 
os.close(); 

刪除那些兩次。到處！它也會關閉插座。
